A Potomac woman pulling out of her driveway Sunday night struck her 7-year-old daughter, leaving the child with critical injuries, Montgomery County police said. They said the mother thought the girl was inside the house.

Wenhua Song, 41, of the 9900 block of Potomac Manors Drive, left her house to go to the grocery store about 9:15 p.m., police said. Her two daughters — ages 7 and 16 — planned to stay home.

But police said they think the younger daughter may have decided at the last minute that she wanted to go with her mother. As Song left the driveway, police said, her 2007 Mercedes-Benz GL450 struck her daughter, Xitong Kong.

TSA plans inquiry

after ammo theft

TSA officials say they are investigating to see whether its procedures for storing ammunition were not followed, after three teenagers were found in a vehicle with 70 boxes of ammunition intended for law enforcement use.

Authorities said the teens — ages 15, 16 and 18 — are suspected of involvement in a break-in early Sunday at a trailer owned by the federal air marshal program, which is part of the Transportation Security Administration. Police said the trailer was in the 7400 block of New Ridge Road in the Hanover area of Anne Arundel County, about one mile from the terminal at Baltimore-Washington International Marshall Airport.

Officials said ammunition is typically stored in a more-secure facility. The trailer had two double locks on it and the ammunition had been left there after it was used in a training exercise on a firing range.

Police said the youths were found just before 2 a.m., seven or eight miles away in the Brooklyn Park area, near Cresswell and Robinwood roads. Their vehicle had been traveling in a suspicious manner, police said. Bolt cutters, flashlights and latex gloves were also found in the car, police said.

Police charged Brandon Michael Shreve, 18, of Linthicum, with multiple counts of theft. A 16-year-old from Glen Burnie and a 15-year-old from Baltimore were also charged.

Man arrested in 1989

Pr. George’s killing

A suspect wanted for a Prince George’s County killing from 1989 is in custody after he was arrested in Georgia, police said.

A Georgia State Patrol trooper arrested Wayne Randolph Gilgeours last week for a minor traffic violation, according to Prince George’s County Police. Authorities suspect Gilgeours of fatally shooting Philbert Jones, 22, in Landover more than 24 years ago.

Gilgeours had a fake ID when he was pulled over, police said. But the Georgia state trooper who pulled him over used a portable fingerprint scanner to positively identify Gilgeours and see he was wanted in Prince George’s County in connection with Jones’s death.

Gilgeours is expected to be transported from Georgia to Prince George’s County, authorities said.
